Abstract
The present invention provides methods for collecting desired cells from a sample using counterflow centrifugal elutriation. Methods of the invention provide for a continuous elutriation workflow with optimized conditions that improves cell purity and retention during the elutriation process. Specifically, methods of the invention use a continuous counterflow centrifugal elutriation process that does not require harvesting cells or removing cells from the separation chamber between elutriation cycles. Methods of the invention increase the purity of desired cell populations, cell number yield, cell recovery, and cell viability to improve downstream processing. Methods of the invention also reduce the volume of buffers and reagents necessary for processing and speeds up the elutriation process for a cost-effective and more efficient cell manufacturing workflow.
